Overview
The MP4050GS is a non-isolated, high-brightness LED driver IC from Monolithic Power Systems. It utilizes a buck topology to drive LEDs with a constant current output of 115 mA. The device operates within an input voltage range of 85 VAC to 265 VAC and features an integrated MOSFET. It supports a switching frequency of 22 kHz and is housed in an SOIC-8 package. The component functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Non-isolated architecture for high brightness LED applications
- Integrated power MOSFET for simplified design
- Constant current output regulation
Applications
- High brightness LED lighting systems
- General illumination drivers
Procurement Notes
Verify the specific suffix (P or Z) as the base model MP4050GS denotes different electrical specifications. The MP4050GS-P variant has a narrow 4.5V to 4.7V input range and 5mA output, while the MP4050GS-Z variant accepts 85VAC to 265VAC with 115mA output. Confirm the required operating parameters before procurement to ensure compatibility with the target circuit design.
Selection Notes
Select the MP4050GS-Z variant for AC mains-powered non-isolated applications requiring higher current. Choose the MP4050GS-P variant only if the application strictly requires a low-voltage DC input between 4.5V and 4.7V. Ensure the selected package matches the PCB footprint requirements for the SOIC-8 form factor.
Part Context
This component belongs to the MP4050 series of LED lighting driver ICs manufactured by Monolithic Power Systems. The series includes variants designed for different input voltage ranges and output currents. The GS designation indicates the SOIC-8 surface-mount package configuration used for these driver circuits.
Replacement Considerations
MPS recommends the MP4050A for new designs instead of the NRND MP4050GS-P. Verify pinout and thermal characteristics when substituting other MP4050 series variants.
